SPECIFICATION forming part .of Letters Patent No. 284,904, dated September- 11, 1883.

Application filed February 8, 1883. (Model.)

' of the construction and operation of the invention, reference being had to the accompanying drawings, in which- Figure l is a side view, being shown in dotted lines. Fig. 2 is a plan view, the screw-threadsbeing shown in dotted lines. Figs. 3, 4, 5, 6, 9, 10, 11, and 12 are detail views of the threading and cutting tools; and Figs. 7 and 8 are detail views of the wrench, the tools shownA in the detail views being interchangeable in thesocketed sleeve.

This invention has relation to pipe fitting and threading machines; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claim appended.

Referring by letter to the accompanying drawings, A designates the Vbody of the machine, the rear arm, A', of which carries a sleeve or bearing, A2, the rear portion of which is decreased in size, and is internally threaded at a, to form a threaded bearing for the enlarged portion of the operating-rod B, the enlarged portion a of this operating-rod B being provided with a right-hand thread, while the forward portion, b', is smaller, and is provided with a left-hand thread to fit the threaded aperture c in a socketed sleeve, C, in order that when the operating-rod B is moved by' turning its handle d2 the sleeve C will be projected when the handle is'turned to the right, and will be retracted within the sleeve A2 when the handle is turned tothe left to adj ust the socketed sleeve C, which carries the interchangeable cutting and threading tools or dies,

5 or wrench, as the caseinay be.

Thus it will be seen thatwhen the rod B, carrying the righthand thread, is screwed up in its threaded bearing, that portion carrying the left-hand thread will simultaneously engage the threads of the sleeve() and drive the same forward at the screw-threads' a rapid motion. The forward end, B', of the body A is curved upwardly and rearwardly, as shown, and is provided with a set-screw, b, -at its upper portion, and a shoulder, b2, almost vertically beneath the bearing for the set-screw bin its lower portion, against which f the threading or cutting tools E and G abut, and are held in place when the tool is to be used. The socketed sleeve C has a. perforation, d', through which a screw, d, is passed into a seat in the stem of the cutter or threading device, or wrench, which occupies the socket in the sleeve C, and a longitudinal slot, f, is made at a point ninety degrees distant from this threaded perforation d in the Yface of the sleeve C, to receive the point of a guidescrew, g, which permits a longitudinal motion of the sleeve C, but prevents a rotary motion of the same in its bearing A2. A threaded nut, J, sleeve A, and is designed to regulate the cutter or threader to pipes of different sizes by turning it to and fro upon the shaft B and securing it in place, when the adjustment has been`reached, by a set-screw, i.

As before stated, the threading-tools, cutting-tools, and wrench are interchangeable. and the sleeve Gis fed forward and backward by the left-hand screw in the direction that the right-hand screw is turned.

Idesignates a screw-driver, having a crosspin for turning the nut J, which has perforations for Iits reception, the driver itself being used to remove and insert the screws.

' Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with the body A, having the sleeve A2, threaded at its rear end, the curved portion B', having the shoulder b2, and the set-screw b, of the operating-rod B, having the right-hand-threaded portion a and the left-hand-threaded portion b', the socketed sleeve C, having slot j', perforation d, set` IsAAC W.

is screwed upon the shaft B, in rear of the.
